The earth is getting darker and darker, and the albedo of the earth drops obviously. Is it related to climate warming?

Experts speculate that the darkening of the earth is due to the increase in electricity consumption caused by long-term air conditioning in some households in the United States, and the increase in power supply in power plants has freed up land.

The ball is at a loss. According to the climate in the United States, it is enough to turn on the air conditioner for only two hours at noon every day in summer, but many American families and businesses stay up all night.

Turn on the air conditioner and turn off the power 24 hours a day, which has caused serious environmental pollution! ?

In addition, some people admit that the developed meat farming in the United States has also caused quite serious environmental pollution, and the mechanized production process is instructive.

A lot of electricity is wasted.

An expert predicts that if the United States abandons mechanized industrialization, it will not only save a lot of electricity, but also create more jobs for the people.

Let's return to nature and protect our planet.

Here we call for saving the earth and saving America! Please Americans don't be stubborn. Americans don't turn on the air conditioner, let alone eat meat. It would be better if we could go back to the ancient life, and rest at sunrise and sunset, so that our mother earth will live longer! ?

Here, I also solemnly suggest that the environmental protection girls in Sweden should hold a press conference immediately after seeing this news and strongly condemn the United States which is not environmentally friendly.

People, advise them to get lost. Climate warming is indeed an imminent problem, not an alarmist by meteorologists. A large part of the global albedo decline is caused by the melting of the ice sheet. Known as the roof of the world, the Pruogangri Glacier in China is also melting, which makes the Selinko in the south expand from 1.667 square kilometers in the 1980s.

Zhang to the current 2394 square kilometers, an increase of about 43%.

The Pruogangri Glacier, with an area of 422 square kilometers and an ice thickness of more than 200 meters, reports that the glacier area in the Qinghai-Tibet Plateau and its adjacent areas has decreased from 53,000 square kilometers to 45,000 square meters in the past 30 years.

Kilometers, shrinking 15%.

There are more than 46,000 glaciers in China, mainly distributed in the Qinghai-Tibet Plateau.

Some researchers predict that most glaciers and frozen soil on the Qinghai-Tibet Plateau will disappear soon. Recently, a new study published in the journal Geophysical Research Letters of the American Geophysical Union shows that,

Climate change leads to the warming of the oceans and the reduction of bright clouds over the earth, which reduces the light reflected into space. The earth is

Absorb more energy than before, which may accelerate climate change and lead to global warming.

Researchers at the New Jersey Institute of Technology in the United States

By analyzing the light reflected by the earth to the surface of the moon and the data measured by satellites, it is found that the albedo of the earth is obvious in recent 20 years.

With the decline, the earth is getting darker and darker. Scientists say this discovery is very worrying because researchers had hoped that the earth would change.

Warming may produce more clouds and higher albedo, which will help to slow down global warming, but now it seems that the actual situation is just right.

On the contrary, this is the moraine lake left by the shrinking of the Midui Glacier in bomi county, Linzhi City, Tibet on April 9, 20 16. Xinhua News Agency reporter Liu Dongjun photographed by the Qinghai-Tibet Plateau Research Institute of China Academy of Sciences, a historical conceptual model of the melting intensity of ancient glaciers in the past 2,500 years was reconstructed for some glaciers on the Qinghai-Tibet Plateau.

The energy input into the earth's climate system mainly comes from sunlight, that is, short-wave radiation.

If it's ultraviolet and visible light. The output energy comes from the earth's own thermal radiation, that is, long-wave radiation, mainly in the infrared band. According to Stefan-Boltzmann law, the intensity of thermal radiation generated by an object is directly proportional to the fourth power of thermodynamic temperature, so

According to the average temperature of the earth's surface, the radiation intensity emitted by the earth into outer space can be obtained. Solar radiation is also calculated in this way, but it is made up of

Because the sun is far away from us, the solar radiation emitted by the surface has been attenuated a lot when it reaches the earth, so the two can basically maintain a balance.

The balance of radiant energy on the earth's surface is roughly as shown in the following figure: when the albedo of the earth's surface increases, it means that the earth's surface reflects more sunlight. If we look at the earth from outer space, we will feel it.

The earth is brighter and brighter. On the contrary, the reduction of surface albedo will make the earth look darker from space. Resulting in a decrease in surface albedo.

There are many reasons, including shrinking glacier area, decreasing cloud cover and increasing smog. The direct consequence of albedo reduction is the ground.

The ball absorbs more solar energy, so in order to achieve a new energy balance, it is necessary for the earth's surface to heat up and emit more thermal radiation.

It can be said that "global darkening" is an inducement of "global warming".

Sunlight reaching the earth will be absorbed by atmospheric molecules, clouds and aerosol particles, and will also be absorbed by the ground. Glaciers melt, exposing

The coming seawater or land absorbs sunlight more easily than glaciers; Many aerosols can absorb sunlight and black carbon aerosols, such as various mountain fires and factory emissions, which are easy to produce and have strong absorption capacity; Absorption of atmospheric molecules, if carbon dioxide or its

With the increase of greenhouse gas concentration, this item will increase. These are all factors that can promote "global darkening".

Generally speaking, it is still very difficult to study the earth's climate system at present because the temperature environment suitable for human habitation is too harsh. As an average whole, the earth's atmosphere must maintain a strong stability, and many uncertain factors brought by human beings may break through this stability, such as the concentration of greenhouse gases and atmospheric pollutants, which directly or indirectly affect the energy budget on the earth's surface and increase atmospheric instability, thus leading to the increase of extreme weather events and natural disasters.

It can be said that climate warming has long been a scientific knowledge, and how to solve this problem is not something that scientists can complete and need.

Cooperation between governments and people all over the world. As an ordinary person, you can try your best to save resources and do some small things that you can, not necessarily.

Force, but please don't drag your feet to promote those anti-science conspiracy theories.
